To all whom; it may concern: V

Be itlniovvnthat I, CHAnLns L. MdDo AL, a citizen of theUnited' States,-residing at Monticello, in the county ot'Law'rence and State ofMississippi, have invented certain new and useful Improvements inSpringminimizing the heretofore laborious Work associated With theoperation of snch deintention is 'disclosedrbrthe' purpose-o1": im-rvices.-

The invention contemplates a main drive shaft having: positionedthereupon and aflixed thereto the 'propellmg spring,vsaid drive shafthaving keyed thereto, a master,

or drive gear, which is, through the medium of a trainof gears, adaptedto impart'a rotary motion to a vertically disposed shaft, which isadapted to .rece ivefthe npper end of the 'chu'rn' operating handle;further, to mount upon one of the horizontally arranged 'shafts u'sed'inconjunction Withthe gearing, arotary fan, for thec'onvenien'ce of theoperator. V r

It' is also amongthe aim's'and-"olojects of the invention to provide asignal or alarm mechanism, which mechanism i's'so actnahle as to operatea signal when the propelling spring has'unw'oundto a predeterminedoextent; also, to provide a controlling handle whereby the movement of thepro elling springmay be'minutel rewlated; v a

[Arranged adjacent the "side pieces 2 and, affixedthereto; reverti Cally disposed gearing supporting" standards 5 'and6while s'e'ic-nre'd to andis pportedny one of the side pieces 2" is aright angularly disposed bracket arm" 7; the purp'o e' of whichshall behereinafterjdescribed; Posi timed between: the -vjertica1 ,sap ortingtandards 5 and: 6 a d 1'p'ut' nal a in suitable bearings, providedforjin the sitlepieeesiajs atran'sversely arranged shaft 8, s'a'idsha'ft having a sqnar'edend portion, as 'at 9. and havingarrangedthereupon andkeyedthere to a driving gear: 10, which g ar has'posi tio'n'ed adjacent thereto and ecured" to the same; theconventional manner, as ommon to this particular art, a

propelling sprin 111; which m y be in the form of the ordinary coiledsp'ri'ng' inaho'v'e said transverse shaft 8 and -prefe'rahly in verticalali nefment the with, is a trans verse Shaft"12',,Which shaft; hasarranged var-iat'ly sed forstchtpa poses, Arranged there'on andkey'edthereto driven ear 13 and a drivin gear 1'4; the latter being f diametergreater". the former; [The shaft; 12 is provided with an elongated' xtension, as designated 1 at '15; which shan'be e subsequently described.Positioned above the shaft 12 and journaled within the supportingstandards 5 and 6 is a similar shaft 16, which shaft has arrangedthereon and keyed thereto driven and driving gears 17 and 18,constructed in accordance with the gears 13 and 14, while arranged abovethe shaft 16 and also journaled within suitable bearings in thesupporting standards 5 and 6 is a transversely arranged shaft 19, thisshaft being of a greater length than the shafts 12 and 16 and havingkeyed thereto a driven gear 20, a balance wheel 21, a beveled gear 22,and a rotary fan 23, the fan being positioned at the extereme outer endof said shaft.

In order to provide for auxiliary supporting means whereby the beveledgears 22 may be rigidly supported, I provide an angularly disposedbracket 24, which is secured to the vertical supporting standard 6, bysuitable fastening devices. Positioned on a suitable bearing arranged inthe bracket arm 7 is a vertically disposedshaft 25, which shaft extendsupwardly and has arranged on its upper end and keyed thereto a beveledgear 26, which is constantly meshed with the beveled gear 22, while thelower end of the shaft 25 has arranged thereon a circular member 27,which serves to support flexible members 28, these members serving asmeans for shooing flies away, while the end of the shaft is preferablymade hollow, to receive the operating handle 29 of a churn dasher 30,which dasher is mounted within the usual receptacle 31, used inconjunction with churns. The operating handle or rod 29 is securedwithin the hollow or socket portion of the shaft 25 by means of a cotterpin 32, which is passed therethrough. Pivotally supported as at 33, uponone of the side members 2, is a controlling arm 34, which normallyengages with the gear teeth of the driving gear 10, and is provided witha handle portion 35, which portion is acljustably received by the teethof a rack 36 which is secured to one of the end pieces 3 as at 37.

In devices of this character, it is highly desirable to provide forsignaling means for indicating when the spring motor has become unwound,and to this end I provide a substantially bell crank lever 38, which ispivotally mounted between ears 39' carried by the vertical supportingstandard 6, and extends through an opening 40 arranged adjacent theretoin the said standard 6 into 7 close proximity with the driving spring11,

while the upper end of the lever 38 is provided with a right angularlydistended arm 41, having a portion 42 bent at angles thereto as shown toadvantage in Fig. 5, which portion 41 is adapted to engage with a starwheel 43, splined to the elongated extension of the shaft 12, as at 44,thereby causing sprlng.

said star wheel to be'moved outwardly. Arranged above the shaft 12 andsupported by the vertical standard 6, is a distended supporting arm 45,which arm has pivotally secured thereto a bell striking hammer 46, whichis adapted to strike a bell 47, also suitably mounted upon the verticalsupporting standard 6.

Means may be provided whereby the shaft 8 may be rotated so as to windthe spring 11, thereby providing for the necessary tension, in form of acrank handle 48.

The operation of the device is as follows: assuming that the spring 11has been wound and that the controlling lever 34 has been disengagedfrom the driving gear 10, it will be seen that motion will be impartedto the shaft 19 by means of the train of gearing, thus rotating thefan-23 and the beveled gear 22, which gear due to the fact that it ismeshed with the beveled gear 26 upon the vertically disposed shaft 25,will rotate said shaft 25, which motion will be imparted to the dasher30 also causing the fiy shooing arrangement to be operated. Uponcontinued rotation of the driving wheel pin the spring 11 will beunwound, consequently causing the same to expand and to engage thatportion of the bell crank lever 38 which extends into its path, causingthe bell crank lever with its projection 41 to be moved forwardly, thusmoving the star wheel 43 and causing the same to engage with the bellstriking hammer 46, intermittently 0 erating the same and causing thebell 4 to be rung, whereby the attention of the operator may beattracted and thecrank 48 may be applied to the square end of the shaft8 whereby the spring 11 may be rewound for a subsequent operation.

In accordance with the provisions of the patent statutes, I havedescribed the preferred embodiment of my invention, together withapparatus which I now consider to represent the preferred form of myinvention, but I desire to have it understood that the same is onlyillustrative and that different arrangement of the parts from thoseshown and described may be resorted to together with mechanicalequivalents for some or all of said parts as may be in keeping with thehereto appended claims.

I claim:

1. In a spring motor, a counter-shaft arranged adjacent the drivingshaft of the motor and intergeared therewith, an audible signalarranged'in proximity with said counter-shaft, signal operating meansmovably mounted upon the counter-shaft, and

a lever arranged upon the'motor frame en- 5 gageable with saidoperatingmeans and the motor spring for moving the operating means intoposition for operating the audible signal upon expansion of the motor 2.In a spring motor having a countershaft arranged adjacent the drivingshaft thereof and intergeared therewith, an audible signal arranged inproximity to said counter-shaft, a hammer for said signal, a star Wheelslidably mounted uponthe counter-shaft engageable at times With saidhammer, and a lever arranged upon the motor frame engageable With saidstar Wheel and the motor spring for moving the Copies of this patent maybe obtained for five cents each, by addressing the Commissioner ofPatents,
